Problems solved by technology

[0002] Excreta produced by virus-infected and carriers, kitchen waste, and sludge from medical sewage treatment have high organic matter content, large production volume, possible virus-carrying, non-toxic substances, and high oil, salt, and nitrogen, phosphorus, and potassium contents. Features. The existing incineration treatment and landfill treatment are likely to cause secondary environmental problems, and the economy and sustainability are poor. For example, centralized or distributed on-site treatment can greatly reduce the social cost of waste treatment , to reduce the risk of virus transmission
[0003] There are mainly three conventional treatment methods for kitchen waste in my country, namely anaerobic fermentation, aerobic composting and feed technology. Advantages, but it is easy to produce odor and takes a long time to process. Feed technology is less used and it is easy to cause secondary problems such as plague.

Embodiment 1

[0018] A method for treating kitchen waste based on ultra-high-temperature aerobic composting technology, which is prepared from the following main raw materials in parts by weight: 26 parts of kitchen waste, 20 parts of sludge, 35 parts of leaves, and 120 parts of mud fungus.

[0019] Described a kind of method based on ultra-high temperature aerobic composting technology processing food waste is operated by the following steps:

[0020] (1) Mix 26 parts of food waste with a moisture content of 80%, 120 parts of mud fungi with a moisture content of 29% and thermophilic bacteria, 35 parts of leaves with a moisture content of 72.3%, and 20 parts of sludge with a moisture content of 50% and put them into fermentation Tank for aerobic fermentation;

[0021] (2) Open the pre-buried pipeline at the bottom of the tank to aerate the pre-fermented garbage heap with oxygen;

[0022] (3) Use a forklift to turn the tank 6 times during the fermentation period to make it evenly mixed;

Abstract

The invention discloses a method for treating kitchen waste based on an ultrahigh-temperature aerobic composting technology. High temperature generated in the pre-fermentation process at the earlier stage of thermophilic bacteria compost fermentation is used for sterilization, and then the thermophilic bacteria are subjected to tank turning treatment, so that the kitchen waste with viruses is turned into an organic fertilizer in a safer, more efficient and more environment-friendly way. The operation involves the following raw materials in parts by weight: 26-52 parts of kitchen waste, 20-40 parts of sludge, 35-70 parts of leaves and 120-240 parts of sludge bacteria. Compared with an existing kitchen waste treatment method, the method saves cost, is convenient to operate and is suitable for nationwide popularization.

Description

technical field [0001] The invention belongs to the field of garbage treatment, and in particular relates to a method for treating kitchen garbage based on ultra-high temperature aerobic composting technology. Background technique [0002] Excreta produced by virus-infected and carriers, kitchen waste, and sludge from medical sewage treatment have high organic matter content, large production volume, possible virus-carrying, non-toxic substances, and high oil, salt, and nitrogen, phosphorus, and potassium contents. Features. The existing incineration treatment and landfill treatment are likely to cause secondary environmental problems, and the economy and sustainability are poor. For example, centralized or distributed on-site treatment can greatly reduce the social cost of waste treatment , to reduce the risk of virus transmission.
